当你在C++中遇到错误 'unordered_map' in namespace 'std' does not name a template type 时,这通常意味着编译器无法识别 std::unordered_map。这个问题可能由几个不同的原因引起。以下是一些可能的解决方案,你可以按照这些步骤逐一排查: 确认已包含必要的头文件: std::unordered_map 需要包含头文件 <unord...
解决办法:error: ‘unordered_map’ in namespace ‘std’ does not name a template type,加上编译选项:g++-std=c++11
